DEVICE FOR PASSING- CABLES THROUGH PIPE-LINES.

Specification of Letters Patent.

Patented J uly 23, 1912.

Application filed April 15, 1910. Serial No. 555,693.

To all whom it may concern:

Be it known that I, BURT B. HODGMAN, a citizen of the United States, and a resident of East Orange, county of Essex, and State of New Jersey, have invented certain new and useful Improvements in Devices for Passing Cables Through Pipe-Lines, of which the following is a specification.

This invention relates to devices for pass ing cables through pipe mains, and is addressed particularly for use in connection with the passing of cables through water mains. In practice, it has been found that where a single cup carrier has been used for this purpose, the passing of same through water mains would be difficult if there was any lateral connection with the main through which it was passing, as the flow of water either into the main from the lateral connection or from the main into the lateral connection would have a tendency to stop the passing of the carrier. To overcome this, two carriers have sometimes been used, and I am informed that sometimes a single carrier the cup of which is deeper or longer than the diameter of the pipe through which it is passing, has been used. It is to overcome the objections to this latter form and the objections to the single and double cup carrier that my invention is addressed.

In the drawings, forming a part hereof, Figure 1 shows my improved form of carrier located within a section of pipe; Fig. 2 is a cross section looking in the direction of the arrow, on line aa of Fig. 1; and Fig. 3 is a modification of my invention.

In the drawings, I have shown the preferred form of my invention in Figs. 1 and 2, in which 1 is a shaft having an eyelet 8 to which may be attached the cable which it is desired to pass through the pipe line. Mounted upon this shaft 1 and held in place by the pointed head 2 and the ribs 5fi5, is a cup having two compartments 3, 3*, connected together by a passage 11. This bowl or cup with two compartments may be made of any suitable flexible material such as leather, thin metal, etc. When made of leather, -I sometimes provide a band 4 surrounding the passage 11 connecting the compartments 3, 3*, although this is not essential. I also sometimes provide a flexible ring 10 shown in the dotted lines in Fig. l, for retaining the compartment 3 in its normal position. The ribs 55, the inner ends of which are attached to the shaft 1 by bolts 6, and the outer ends of which are attached to the cup by rivets 7, may be of any suitable material so as to prevent the inversion of the cup, and at the same time retain the cup in its normal position without being too rigid.

In Fig. 3, I have shown a modification in which I have constructed a single cup of leather or other suitable material, and formed the same into two compartments 3 and 3*, by fastening a rope i around the center of the cup, drawing this part together so as to form a smaller compartment or passage connecting the two larger compartments 3 and 3 The advantage to be derived in constructing a carrier in accordance with my invention is that you get the advantages of a single cup, the advantages of a double cup, the economy in construction, and at the same time minimize the friction created by the passage of the carrier through the pipe.

Modifications and changes might be made without departing from my invention, such, for instance, as dispensing with the shaft 1 and attaching the cable directly to the cup by the rib 12, as shown in Fig. 3.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is:

1. In a device for passing cables through pipe lines, the combination of a shaft, a cup mounted thereon, said cup being formed in two compartments.

2. In a device for passing cables through pipe lines, the combination of a shaft, a cup mounted thereon, said cup being formed in two compartments, and a passage connecting said two compartments.

3. In a device for passing cables through pipe lines, the combination of a flexible cup formed in two compartments, and means for retaining said compartments in their normal position.

4:. In a device for passing cables through pipe lines, the combination of a flexible cup having two compartments, means for retaining said compartments inv their normal position, and a passage connecting said compartments.

5. In a device for passing cables through pipe lines, the combination of a shaft, a cup mounted thereon having two compartments, In testimony whereof, I have signed my one lying directly ahead of the other. name to this specification, in the presence of a 6.
